WILLIAM J. DAMMLING, OF WEST HAVEN, CONNECTICUT.

ROUNDABOUT.

Patented June 6, 1911.

Application filed January 18, 1911. Serial No. 603,357.

To all whom "it may concern:

Be it known that I, NILLIAM J. DAMM- LlNG, a citizen of the United States, residing at West- Haven, in the county of New Haven and State of Connecticut, have in vented a new and useful Improvement in Roundabouts; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1 a side view partially in section of an amusement device constructed in accordance with my invention. Fig. 2 a plan viewof the first revolving platform with the mechanism for driving the second platform removed, and the inner ends of the shafts and bearing block therefor broken away. Fig. 3 a sectional view on an enlarged scale of the driving mechanism. Fig. 4 a sectional view illustrating the manner of suspending the upper platform to the post.

This invention relates to an improvement in amusement devices of the roundabout type, and articularly to that class in which one set of carriers is caused to revolve on a horizontal axis and another set to revolve on a vertical axis the object of the invention being to provide a combination of devices in a simple and convenient manner and which will be sufficiently strong to stand the necessary strain; and the invention consists in the construction and combination of parts as will be hereinafter described and particularly recited in the claims.

In carrying out my invention I employ a central post 2 firmly embedded in a suitable foundation 3 and so as to be held against rotation, and above the foundation is a circular platform 4. Surrounding the post and supporting the same is a frame 5 formed from angle irons suitably staid. This framework supports a circular track 6, and turning on this track is a first revolving platform 7 Access to this platform is had through a spiral staircase 8 inclosed in a housing 9 having an entrance opening 10. This housing is supported on the platform 4 and is provided with wheels 11 to run on the platform 4. Opposite the staircase 9 is a slide or chute preferably made of glass and supported by suitable wheels 13 to roll on the platform 4. Loosely mounted on the post 2 and supported by the transverse bar 14 of the frame, is a gear-wheel 15, and meshing with this gear 15 is a gear 16 fixed to the power shaft 17 by which it may be turned from any convenient point. Above the gear 15 and carried by it is a fourarmed yoke 18 carrying bevel gears 19, 20, 21 and 22 which mesh with a horizontal bevel gear 23 keyed to the post 2. The bevel gears 19, 20, 21 and 22 are fixed to radial shafts 24, 25, 26 and 27 each of which carries a so called Ferris wheel 28, these wheels having passenger seats 29 in the usual manner of wheels of the Ferris type; and the radial shafts are supported by rollers 30 which ride on the first circular track 6. The first revolving platform 7 is connected by sleeves 43 wit-h the radial arms and consequently as the arms rotate the platform will be rotated with them. This platform is inclosed by a circular wall or railing 31 within which is a bicycle track or space for other devices.

Projecting upward from one of the arms of the yoke 18 is a stud 32 carrying a small pinion 33 which meshes with a gear 34 fixed to the post 2, and above the gear 34 is a pinion 35 fixed to a sleeve 36 free to turn on the post 2, the pinion 35 meshing with a pinion 37 which is also loose on the stud 32, the pinions 33 and 37 being coupled together and so that as the yoke revolves the sleeve 36 will be turned accordingly but in the direction opposite to that in which the yoke is turned. This sleeve 36 supports the second revolving platform 38 which, as will be seen, turns in a direction opposite to that of the first revolving platform 7, and this platform receives its main support through rods 39 fixed to a head 40 which rests upon a tubular bearing-sleeve 41 sitting over the upper end of the post. the platform 38 seats of any desired style will be placed, and access to the second revolving platform is had from the first. re- .volving platform by means of removable steps 42. The yoke 18 and gearing connected therewith, will be inclosed in suitable casing 43. Passengers will be admitted to the Ferris Wheels from the platform 4, and passengers for the upper platform will enter by the spiral staircase 8, and to the second revolving platform by the steps 42. When loaded powenbeing applied through the shaft 17 will turn the several Ferris wheels and rotate the platform 7 in'one directidn and the platform 38 in the opposite direction and at the desired speed, the steps 42 being removed when the mechanism is started in motion; and when the mechanism stops passengers from the two platforms may be discharged by the staircase or through the chute 12.

I claim 1. An amusement device comprising a fixed central post, a framework surrounding the same, a bevel gear fixed to the post, a four-armed yoke free to turn on the post, radial shafts carried by said yoke and each shaft having a beveled gear meshing with the fixed gear on the post, means for revolving said yoke, passenger-carrying wheels fixed t0 the outer ends of each of said shafts, a first revolving platform connected with said shafts and adapted to be turned therewith, a second revolving platform suspended from the top of the post above the first revolving platform, and means for rotating the same in a direction reverse to that of the first platform.

2. An amusement device comprising a fixed central post, a framework surrounding the same, a bevel gear fixed to the post, a four-armed yoke free to turn on the post,

radial shafts carried by said yoke and each shaft having a beveled gear meshing with the fixed gear on the post, means for revolving said yoke, passenger-carrying wheels fixed to the outer ends of each of said shafts, a first revolving platform connected with said shafts and adapted to be turned there-with, a second revolving platform sup ported from the top of the post above the first revolving platform, a sleeve connected with the underside of said second revolving platform the lower end of the sleeve having a gear meshing with a gear carried by said yoke, and a gear fixed to the postbelow the said sleeve and meshing with a gear carried by the yoke whereby the second plat-- form is caused to rotate in a direction opposite to the direction of rotation of the first revolving platform.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
